CHURN.

SPECIFICATION forming part of Letters Patent No. 433,507, dated August 5, 1890.

Application filed April 17, 1890. Serial No. 348,296. (No model.)

To all whom it may concern:

Be it known that I, FREDRIOK H. WVOLF- MYER, a citizen of the United States, residing at La Grange, in the county of Lewis and State of Missouri, have invented a new and useful Churn, of which the following is a The invention relates churns.

The object of the present invention is to provide a simple and inexpensive churn adapted to be easily and readily operated and capable of quickly converting the lacteal fiuid into butter.

A further object of the invention is to provide a churn in which the parts may be readily assembled and separated when desired.

The invention consists in the construction to improvements in and novel combination and arrangement of parts, hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure 1 is a perspective View of a churn constructed in accordance with this invention. Fig. 2 is a central vertical longitudinal sectional view. Fig. 3 is a similar view taken at right angles to Fig. 2. Fig. 4 is a detail view of the hook and loop for securing the body of the churn to the frame.

. Referring'to the accompanying drawings, 1 designates a rectangular frame composed of similar beams 2,having their ends secured together and to vertical standards 3, that support the frame and are arranged at the corners thereof.

Mounted upon the frame is a churn-body 4, which is provided upon its lower face with a loop 5, that is arranged to be engaged by a threaded hook 6, that is mounted in a crossbar 7 of the frame and is provided with a thumb-nut 8, adapted to tighten or release the hook and securely retain the churn-body 4 upon the frame and enable it to be removed therefrom when desired, and the threaded hook 6 is preferably provided with a washer or perforated block 9 to facilitate the adjustment of the hook. The frame is provided on its upper face with guide-blocks 10, which fit against the sides of the body when the latter is in position and enable the same to be readily adjusted to its proper position an d they steady the body and prevent the same slipping when the parts are assembled.

The churn-bod y is preferablybarrel-sha ped, but may be of any desirable construction, and is provided with a vertical tube or pipe 11, that is centrally arranged and projects sllghtly above the body, and has its lower end secured in a central opening 2 of a plate or strap 13, that is secured to the lower face of the bottom of the churn-body.

\Vithin the vertical tube/11 is arranged a connecting-rod 14:, that has at its upper end 15 threaded and secured to dasher-rods 16, and its lower end 17 bent laterallyand connected to a pitman 18, the other end of which is secured to the arm 19 of a crank-shaft 20. The crank-shaft 20 is mounted in suitable bearings 21 and 22, depending from one of the beams 2 of the frame and a cross-bar 23, and

provided with a pulley or similar means and be connected with any desirable motive power. The upper end of the connecting-rod 14 1s secured in a central threaded opening 27 of a cross-piece 28, formed integral with the dasher-rods 16. The dasher-rods 16 are arranged parallel with each other, and are located on opposite sides of the vertical tube, and are adapted to be moved vertically, and they have their lower ends 29 threaded and provided with nuts 30, that securea disk-shaped dasher 31 to the dasher-rods. When the cog-wheel 25 is turned the crankshaft is rotated, and by means of the pit-man 18 vertical movement is communicated to the connecting-rod 14, which carries the parallel dasher-rods 16 and the dasher 31 with it, and the lacteal fluid is quickly converted into butter.

The churn-body is provided with a cover 32, that is provided with a central opening 33, to receive the central tube, and openings 34, in which the parallel dasher-rods 16 are arranged, and the latter move vertically through the cover which supports the rods and the tube and prevents them becoming canted during the operation of the churn. The crosspiece 28, which is formed integral With the dasher-rods, prevents the cover slipping off the rods, and the said cover, dasher-rods, and dasher are secured together and are adapted to be applied to the body and removed therefrom simultaneously, and in order to secure the dasher-rods to the connecting-rod it is only necessary to engage the upper threaded end of the connecting-rod with the central threaded opening of the cross-piece. The cover 32 is provided with an eye 35, which is arranged at the edge, and is adapted to be engaged by a hook 36, secured to the side of the churn-body to fasten the (30"81 in place.

It will readily be seen that the churn is simple and inexpensive in construction and is adapted to be readily operated and is capable of having its parts readily assembled and separated.

\Vhat I claim is 1. In a churn,the combination of the frame mounted upon vertical standards, the rigid churn-body secured to the frame and provided with the vertical tube 11, the connecting-rod 14, arranged in the tube and extending through the churn-body and having its lower end connected with suitable operating mechanism, and the parallel dasher-rods connected outside of the churn-body with the connecting-rod and having their lower ends secured to a dasher, substantially as described.

2. In a churn, the combination of the frame mounted upon vertical standards, the rigid churn-body secured to the frame and provided with the vertical tube 11, the connecting-rod 14, arranged in the tube and extending through the body, the parallel dasher-rods 16, having their lower ends secured to a dasher and connected outside of the churn-body with the rod 14, the crank-shaft provided at one end with a pinion, the pitman connecting the rod 14 and the crank-shaft, and the cog-wheel 25, meshing with the pinion, substantially as described.

3. In a churn, the combination of the frame, the rigid churn-body suitably secured thereto and provided with a vertical tube 11, the rod 14, extending through the body and having its lower end connected with suitable operating mechanism and having its upper end threaded, the dasher-rods 16, arranged parallel with each other and located upon opposite sides of the tube 11 and having their lower ends secured to a dasher and connected outside of the churn with the rod 14 by an integral cross-bar 28, provided with a threaded opening to receive the upper end of the rod 14, and the cover arranged loosely upon the dasher-rods and having a central opening to receive the tube 11, substantially as and for the purpose described.

4. In a churn, the combination of the frame provided with guide-blocks 10, the churnb'ody arranged upon the frame and provided with suitable securing means and having the central tube 11, the rod 14, connected with suitable operating mechanism and extending through the churn-body, the vertical parallel dasher-rods 16, having their lower ends secured to a dasher and their upper ends connected outside of the churn-body with the rod 14 by the integral cross-bar '28,and the cover loosely secured to the dasher-rods and having the openings 33 and 34, and being suitably secured to the churn-body, substantially as described.

In testimony that I claim the foregoing as my own I have hereto afliXed my signature in presence of two witnesses.
